has_js Cookie

What does the has_js cookie do?

The cookie is a flag indicating whether JavaScript is enabled or disabled on the client side. It provides support for functions that depend on JavaScript execution. The has_js cookie is used by Drupal to determine if a visitor's browser has JavaScript enabled.

Why this cookie matters

This cookie is commonly used by drupal-cms , criteo for preferences purposes – such as tracking usage behaviour, optimising experience, or enabling marketing functionality.

Because it's categorised as preferences, many jurisdictions require that users give explicit consent before it can be activated. If blocked or denied by the visitor, preference-related features (like remembering language or layout choices) may not function properly.
